Self-propelled dual-beam bridge maintenance platform

Abstract

The invention belongs to the technical field of bridge maintenance and particularly relates to a self-propelled dual-beam bridge maintenance platform. According to the technical scheme, the self-propelled dual-beam bridge maintenance platform comprises two maintenance rack cars of the identical structure; each maintenance rack car comprises a bridge floor traveling mechanism, a telescopic arm assembly, turning mechanisms, vertical trusses, a detection platform fixing frame, a detection platform telescopic frame and a docking device; the traveling mechanisms are arranged on the two sides of a bridge floor; the head portion of each telescopic arm assembly is connected with the corresponding traveling mechanism; the upper portion of a connecting cross beam of each telescopic arm assembly is provided with the two corresponding turning mechanisms, and the two turning mechanisms are each provided with one vertical truss; the lower portion of each vertical truss is connected with a bottom detection platform; and as for the two maintenance rack cars, the bottom detection platforms can be connected into a whole through the docking devices. The self-propelled dual-beam bridge maintenance platform has the advantages of being convenient and fast to install, capable of being unfolded mechanically, free of occupying the bridge floor and influencing traffic, capable of passing through obstacles on the roadside and pier obstacles, and the like.

Description

technical field [0001] The invention belongs to the technical field of bridge maintenance, in particular to a bridge maintenance vehicle. Background technique [0002] At present, the total number of bridges in our country is growing rapidly, ranking first in the world. The increase in traffic volume, the erosion of the natural environment and accidental damage will all cause unforeseen damage to the bridge, and even cause the entire bridge to be destroyed. Bridge collapse accidents continue to occur, causing great harm and loss to the safety of people's lives and property. In this case, the pressure on bridge maintenance, maintenance, and repair work is also increasing. In recent years, the Chinese government has paid more and more attention to the inspection and maintenance of bridges, requiring the health status of each bridge to be tracked, detected in time, maintained and even reinforced. Since the bottom of the bridge is an air-facing surface, it is difficult for the...

AI Technical Summary

Problems solved by technology

[0004] The simple bridge inspection platform adopts the method of scaffolding and manual assembly, which can meet the use of ordinary small bridges, but it cannot be solved when inspecting some bridges with high height or crossing large rivers and deep canyons;

[0005] The fixed (permanent) bridge inspection platform needs to build the installation track when the bridge is built, but the installation track is not built when most bridges are built, and the adaptability is not wide;

[0006] The mobile bridge inspection platform has a folding bridge inspection vehicle and a truss bridge inspection vehicle. These two types of bridge inspection vehicles have a high degree of automation, fast speed, and can adapt to various bridges. However, there are some inconveniences in the use of bridge inspection vehicles. Disadvantages: (1) The load of the hanging basket is relatively small, the working area is relatively small, and large-scale testing equipment cannot be carried; (2) When obstacles such as street light poles or cable stays are installed on both sides of the bridge deck, in order to avoid obstacles, it is necessary to place the The working arm is frequently put up and down, and the construction efficiency is reduced; (3) Both inspection vehicles have chassis vehicles, and they always occupy the lane during the construction process, which will affect the bridge traffic
